Caroline Elizabeth Sarah Norton (22 March 1808 – 15 June 1877) was an English social reformer and author active in the early and mid-nineteenth century. Caroline left her husband in 1836, following which her husband sued her close friend Lord Melbourne, the then Whig Prime Minister, for criminal conversation. The jury threw out the claim, but Caroline was unable to obtain a divorce and was denied access to her three sons. Caroline's intense campaigning led to the passing of the Custody of Infants Act 1839, the Matrimonial Causes Act 1857 and the Married Women's Property Act 1870. Caroline modelled for the fresco of Justice in the House of Lords by Daniel Maclise, who chose her because she was seen by many as a famous victim of injustice.
Caroline was born in London to Thomas Sheridan and the novelist Caroline Henrietta Callander. Her father was an actor, soldier, and colonial administrator, and the son of the prominent Irish playwright and Whig statesman Richard Brinsley Sheridan and his wife Elizabeth Ann Linley. Caroline's mother was Scottish, the daughter of a landed gentleman, Col. Sir James Callander of Craigforth and Lady Elizabeth MacDonnell, the sister of an Irish peer, the 1st Marquess of Antrim. Mrs. Sheridan authored three short novels described by one of her daughter's biographers as "rather stiff with the style of the eighteenth century, but none without a certain charm and wit..."
In 1817, her father died in South Africa, where he was serving as the colonial secretary at the Cape of Good Hope. His family was left virtually penniless.Prince Frederick, Duke of York and Albany, an old friend of her grandfather's, arranged for Caroline's family to live at Hampton Court Palace in a "grace and favour" apartment, where they remained for several years.
